APPARATUS FOR RESTRAINING MIDDLE PLATE IN PRINTING TYPE CASTING MACHINE

摘要

PURPOSE:To provide the titled apparatus not in danger of making finish of a printing type inferior by constituting so as to restrain a middle plate forming a casting space to its position until a cast printing type is solidified through a corner defining block. CONSTITUTION:When a printing type is cast, a middle plate 7 is cooperated with a wedge 21 located corresponding to the printing type to be cast by a middle plate operating lever 8 to form a casting space 16. By operating a cam 36 for restraining the middle plate 7, an inclined surface 27 of a wedge 28 for restraining the middle plate 7 is brought into contact with an inclined surface of a corner defining block 4 in a slidable manner and the middle plate 7 is restrained to its position through said corner defining block 4 until the cast printing type is solidified. During a time when a molten metal introduced into the casting space 16 under pressure from a running gate 18 is solidified to be molded into the printing type, the middle plate 7 can be restrained to its position.
